Changes in the anomalous Hall resistance of a single device comprising a Ta/CoFeB/MgO heterostructure can be used to probe three-dimensional magnetic fields with high sensitivity and good linearity.
A hydrogel composite that consists of micrometre-sized silver flakes suspended in a polyacrylamide–alginate hydrogel matrix exhibits a high electrical conductivity of over 350 S cm−1 and a low Young’s modulus of less than 10 kPa.
Large-scale sensing textiles that can conform to arbitrary three-dimensional geometries and are created through digital machine knitting of piezoresistive fibres can be used to record, monitor and learn human–environment interactions.
Laser-induced terahertz emission, and time-of-flight measurements of the terahertz pulse, can be used to non-invasively characterize through-silicon vias, which are required for three-dimensional CMOS integration.
Multiple field-programmable gate arrays can be networked to create clustered, scalable architectures that can be used to run partitioned simulated bifurcation algorithms for solving non-deterministic polynomial-time (NP)-hard problems.
A wireless communication scheme based on space- and frequency-division multiplexing using digital metasurfaces
Space–time-coding digital metasurfaces can be used to implement secure and low-cost space- and frequency-division multiplexing in a dual-channel wireless communication system.
